Will you be happier at work with flexible working hours? Why?

It really depends on the person and the role he/she is assigned to. Some people would like flexibility on the matter, since especially if their role requires them to work solo most of the time, it would be better for them to work at their own pace within the given timeframe. On the other hand, other people need to be kept on time scedule, maybe because they can't do it on their own, or because they have to work with other people during their assignments.

Personally speaking, flexibility as far as the working hours matter is concerned, would be welcome, since I like working at my own pace; however, this flexibility wouldn't neccessarily mean that my working hours would be different than others'; it mostly means to me that I have a relative freedom to perform and underconsiously feel like my own boss, hence producing better work output. 

Not necessarily.

I think I may be happy if I work in a promissing & Harmonized Enviroment.

Yes of course that wouls be great that instead of adjuating your variable activities

I would personally be more than happy to work flexible hours and the freedom it presents as I already work long hour. It would require quite a bit of planning, and it all depends on the type of industry you find yourself in. 

I tried it many times. I don't prefer it 

yes, i am happy to work with flexible hours. because we can make a more money in certain limit period. it's benifit for the staff and also good for the company also produce more product in certain time. so, it's good deal for both.

i think i will be very happy

This depends on the business environment in which it operates employee, also depends on team spirit and the nature of the deal direct manager

it depends of the cultural environment, type of business, level of maturity of the organization etc. 

The responsibility for the efficient operation of the scheme with flexible working hours rests primarily with line managers. The operation of the flexi-time scheme is based on the acceptance that the structure’s operational needs take precedence over personal preferences. ( and this is hard to control even when we talk about a standard work program with the employee present at the working place).
